TRACK-SANDING MECHANISM FOR TROLLEY-CARS AND LOCOMOTIVES.

Specification of Letters Patent.

Patented June 18, 1912.

To all whom it may concern:

Be it known that I, HOWARD HAWTHORNE, a citizen of the United States,residing at Philadelphia, in the county of Philadelphia and State ofPennsylvania, have invented certain new and useful Improvements inTrack- Sanding Mechanism for Trolley- Cars and Locomotives; and I dohereby declare the following to be a full, clear, and exact descriptionof the invention, such as will enable others skilled in the art to whichit appertains to make and use the same.

My invention relates to an improvement in track sanding mechanism fortrolley cars, and locomotives, and relates more particu larly to theconstruction and relative arrangement of the parts of such mechanism.

The object of my invention is to provide a device comprising twocompartments, one for the storage and the other for the dis charge ofsand, each compartment being provided with valve mechanism soconstructed and arranged that the openings between the storage anddischarge compartments, and the opening through which sand is dischargedonto the rail ,will be simultaneously governed and controlled.

A further object of my invention is to provide a sanding device in whichthe storage and discharge compartments are superposed and combined incompact form and in which a single valve actuating shaft serves tooperate the valves in both compartments.

A further object of the invention is to provide both the storage anddischarge compartments with valves and valve actuating mechanism andwith means for compensating for the wear of both valves and their seats.

A further object of the invention is to provide a simple, economical,durable and efficient construction of parts, which will occupy verylittle space on a car and is adapted for ready and easy operation.

With these objects in .view my invention consists in certain features ofconstruction and combinations of parts aswill be hereinafter describedand pointed out in the claims.

In the accompanying drawings, Figure 1 is a view in side elevation of myimprovement; Fig. 2 is a vertical section; Fig. 3 is a plan view of thebottom of the storage receptacle; Fig. 4 is a plan view of the0scillating valve for regulating the discharge of sand from the storagereceptacle into the discharge receptacle; Fig. 5 is a transverse sectionof said valve; Fig. 6 is a plan View of the bottom of the dischargereceptacle; Fig. 7 is a plan view and Fig. 8 is a transverse section ofthe valve used in the diS- charge receptacle; Fig. 9 is a view in planof the actuating arm, and Fig. 10 is a view illustrating one arrangementof mechanism for actuating the valves.

1 represents the sand storage receptacle and 2 is the dischargereceptacle both of which may be made of sheet or cast metal and arepreferably cylindrical in form.

Storage receptacle 1 is provided at its upper end with an outwardlyprojecting annular flange 3 having holes 4 formed therein through whichbolts are passed for securing the receptacle to the underframe of a carbody at any desired point thereon. The lower end of receptacle 1 isconstructed with an inwardly projecting annular flange P, to theunderside of which, is secured by bolts 5, the outwardly projectingflange 6, of the valve seat 7 of the storage receptacle.

Discharge receptacle 2 is secured at its upper end to the downwardlyprojecting flange 8 of valve seat 7 by means of screws 9, and tothebottom 10 is secured the discharge funnel 11, which is constructedand arranged to insure the discharge of sand on to the traclerail.

12 is a valve actuating shaft, which is journaled near its upper end ina hole 13 formed in the center of the valve seat 7. To the upper end ofthe shaft 12 is secured two oscillating valves 13, 13, each of which issector shaped and they are connected together by a central hub 14 whichis mounted upon the upper end of shaft 12 and secured thereto by thetransverse pin 1 1 and nut 15. The valve ,seat 7 is provided with twosector shaped ports 16, 16, which are simultaneously opened and closedby the oscillating valves 13, 13. Each of these valves is provided onits upper surface with upwardly project-ing prongs 17 which ongage andstir the sand as the valves are actuated and thereby prevent the sandfrom clogging and cause it to flow freely t-hrouglr the ports 16 intothe discharge receptacle 2.

18 is a sector shaped oscillating valve seated upon the bottom 19 of thedischarge receptacle and arranged to open and close lbs the hub 22 ofthe valve and through the shaft. This valve is constructed with upwardly projecting prongs 23 which serve to stir up the sand in closeproximity to' the valve when the latter is actuated and prevent the sandfrom clogging and insure r and largely assists in maintaining itscontents dry and in conditlon to be readily disits free escape throughthe port 20.

24 is a coiled spring which encircles the lower projecting end of shaft12. The up er end of the spring is seated against a was er 25, the uppersurface of which engages the bottom plate of the discharge receptaclewhile the lower end of the spring is seated upon the washer 26 which issupported by a nut 27. By adjusting the nut the tension of the springmay be regulated and varied as desired. lVhile the weight of the twovalves and their actuating shaft, all tends to retain the valves againsttheir seats, the coiled spring exerts its force to cause the valves tosnugly fit against their seats and preventstheir being displaced due tothe jolting'or jarring of the car over rough tracks, and it also adjuststhe valves to compensate for their wear or that of their seats. Shaft 12is provided with a squared lower end 28 to which is secured the innerend of the actuating arm 29 which is constructed with a square hole 30within which is inserted the squared end of the shaft, the parts beingsecured in place by means of a transverse locking pin 31. A stop pin orlug 32 limits the extent of movement of the arm 29. The arm 29 may beactuated by the motorman by any suitable mechanism. I have illustratedone construction and arrangement of mechanism for this purpose whichconsists of a vertically movable treadle 32 located above the platformof the car and within easy reach of the motorman and with which isconnected a rod 33 which extends downwardly through the platform and ispivotally connected with one arm 34 of a bell-crank lever, the other arm35 of which is connected by a rod 36 with the outer end of the actuatingarm 29. A spiral spring 37 interposed between the treadle and platformserves to retain the treadle in its raised position. Then the treadle isin its raised and normal position the discharge valve 18 will be closedand the valves 13, 13 in the storage compartment will be open, and hencethe lower and discharge compartment will always be kept filled withsand. I Vhen it is desired to sand the track, the'motorman by forcingthe treadle downwardly, transmits an oscillating movement to shaft 12which operates to close the valves 13, 13 and opens the discharge valve18 thus permitting the sand to escape and flow upon the track rails forany desired length of time and during this period preventing the sandfrom flowing from the storage compartment into the lower and dischargecompartment.

My improved device is exceedingly com- 2 act sim 1e and economical inits construction and arrangement of parts. By having the storagereceptacle located immedlately "over. the discharge receptacle and itswalls secured thereto, it shields the contents of the dischargereceptacle from the weather while a single coil spring prevents eitherone of the valves from being jarred from its seat by the jolting orjarring of the car, and also causes the valves to automatically adjustthemselves to their seats and thereby compensate for wear.

Itis evident that slight changes might be made in the construction andarrangement of the several parts of my improvement without departingfrom the invention. I would have it understood that I do not re strictmyself to the particular construction shown and described.

Having fully described my invention what I claim as new and desire tosecure by Letters- Patent, is z 1.
